The product of 3 and a number x is 2/3. This sentence can be reproduced by the expression 3x = 2/3. Our objective is to find x, a constant which if multiplied by 3 gives 2/3. First, we need to have x alone on the side of the expression. So we divide it by 3. we get x = (2/3)/3 When dividing 2 fractions (3 is considered as a fraction since 3=3/1), the answer is equal to the first fraction multiplied by the inverse of the second. So (2/3)/3 = 2/3 * 1/3 (since 1/3 is the inverse of 3) = 2/9
